U.N Secretary-General Ban Ki-moon has said that South Sudan's leaders have failed their people by putting their personal ambitions first and if they do not show willingness to compromise in peace talks they have to face consequences such as sanctions. In his latest report to the U.N. Security Council on Thursday, Ban said the warring parties are recruiting children to fight and restricting the work of U.N. peacekeepers, who are sheltering some 118,000 people at protection sites. Ban said that 16-months of peace talks led by East African bloc IGAD broke down last month "due to the continued intransigence of South Sudan's political leaders and their failure to see beyond their personal ambitions and put the people of South Sudan first.""Should the parties fail to show willingness to compromise, and continue giving priority to military confrontation, those responsible will have to face the consequences," Ban wrote, noting that the U.N. Security Council in February established a sanctions regime for South Sudan.The Security Council threatened to blacklist anyone undermining security or interfering with the peace process in South Sudan, but it has not yet imposed worldwide travel bans and asset freezes on any officials in the conflict-torn country.He called on "President Kiir and Riek Machar to cease all military operations immediately release all children mobilized within their ranks and engage in meaningful dialogue on all outstanding issues towards the establishment of a transitional government of national unity."
